Sorry to hear that. They've been hacked just this day and the filing of bankruptcy really makes sense at all because the remaining funds that's assigned that's likely to pay for their customers, it's no longer there.
I've heard that some has been retrieved but I don't think that this is going to be enough to pay the millions of users that have trusted their funds onto them and sadly, you're one of those. It's a big lesson that everyone will learn from this incident.
